A comprehensive analysis of Drell-Yan production uncertainties and mass effects at moderate and low dilepton masses
Year: 2026
Type: article
Abstract: A bstract We present a thorough investigation of the sources of uncertainties to the Drell-Yan production using state-of-the-art predictions for both neutral and charged current channels, focusing on the low invariant mass region. Differential predictions for the invariant mass spectrum are provided at N 3 LO supplemented with exact charm and bottom quark mass effects calculated at $$ \mathcal{O}\left({\alpha}_s^2\right) $$ O α s 2 . The impact of PDF choices (including approximate N 3 LO), scale variations, the variation of the strong coupling constant, and impact heavy quark mass effects on the distributions is studied in detail. We also comment on the correlation of high-energy astrophysical processes with the low-mass DY region.
